Method of producing synthetic fuels and organic chemicals from atmospheric carbon dioxide

Abstract

The present invention is directed to providing a method of producing synthetic fuels and organic chemicals from atmospheric carbon dioxide. Carbon dioxide gas is extracted from the atmosphere, hydrogen gas is obtained by splitting water, a mixture of the carbon dioxide gas and the hydrogen gas (synthesis gas) is generated, and the synthesis gas is converted into synthetic fuels and / or organic products. The present invention is also directed to utilizing a nuclear power reactor to provide power for the method of the present invention.

Description

STATEMENT REGARDING FEDERAL RIGHTS[0001]This invention was made with government support under Contract No. DE-AC52-06NA25396 awarded by the U.S. Department of Energy. The government has certain rights in the invention.BACKGROUND OF THE INVENTION[0002]The United States is dependent on petroleum and natural gas for about 63% of its energy. The U.S. has less than 2% of the world's petroleum reserves and is drawing down its own reserves at a disproportionately high rate. That is, the U.S. obtains about 40% of its petroleum from domestic sources. It is likely that the peaking of oil production and increasing international demand will drive prices very high. The impact of high prices could have a profound effect on the energy sector and transportation sector. The production of plastics, petrochemicals, and other chemicals will likely also be affected. The transportation sector accounts for around 65% of the U.S. petroleum consumption and the largest components of the transportation sector...

AI Technical Summary

Benefits of technology

The present invention provides a method for producing synthetic fuels and organic chemicals using a combination of extracting carbon dioxide gas from the atmosphere, producing hydrogen gas, and converting the gas to a synthesis gas. The resulting chemical products include synthetic fuels and organic chemicals such as diesel fuel, gasoline, petrochemicals, plastics, and aromatic compounds. The invention also provides a cooling tower for use in the method. The technical effects of the invention include increased efficiency in the production of synthetic fuels and organic chemicals, reduced carbon dioxide emissions, and improved energy utilization.

Problems solved by technology

The production of plastics, petrochemicals, and other chemicals will likely also be affected.

Shifting from a reliance on petroleum to electrical power cannot make up for the loss of fuel and raw materials that will result from declining petroleum availability.

U.S. economic security depends on a stable supply of transportation fuel and chemicals; however, around 78% of world petroleum reserves are found in politically unstable regions.

Increasing world wide competition for dwindling petroleum resources in unstable regions could compromise U.S. energy security.

Alternative fuel sources, such as hydrogen or other liquid fuels, cannot replace petroleum in all of its uses.

Alternative approaches currently being considered generally have an inherently limited capacity and application, significant technical risk, or are prohibitively expense.

Mining coal is environmentally intrusive and exposes the environment to man-made hazards.

Drilling for oil and its transportation exposes the environment to man-made hazards.

Burning fossil fuels produces air pollution and carbon dioxide emissions which may lead to global warming.

However, there are technical obstacles that must be overcome in order to utilize hydrogen as a safe and economical alternative.

Safe, long-distance transportation of hydrogen is expensive.

Implementation of a hydrogen economy requires a massive investment in infrastructure which means massive expense.

Also, hydrogen may be impractical for some applications such as large airliners, long-distance ground transportation vehicles, and large construction equipment.

This is a process that may be used once carbon dioxide gas and hydrogen gas have been obtained, but it does not provide a mechanism for obtaining the gases.

Again these processes may be used once carbon dioxide gas and hydrogen gas are obtained but they do not provide a mechanism for obtaining the gases.

This patent does not disclose the specific source of carbon dioxide, nor does it address energy sources other than solar and wind.

This patent does not address energy sources other than solar and wind.
